Transmission noise questions.

When the body mounts start to sag , the cab of the truck will actually start to rest on top of the transmission . When that happens , it gets very very uncomfortable in the drivers seat . You feel everything the engine and transmission are doing .
Yah , Have a peek at the body mounts for sure . You can even get a bit crazy . With the transmission in drive , hold your brakes really hard and slowly bring the engine revs up to 2000 in forward and then try reverse . You will see something , this I promise .
Allow the truck to idle afterwards so your transmission has a chance to cool .
Its called a stall test . We do this all the time for diagnostic purposes only ofcourse

 

Body mounts pretty easy to replace??
